PROPELLING DEVICE.

Specification of Letters Patent.

Patented April 24, 1906.

Application filed December 1, 1904. Renewed November 2, 1905. Serial No. 285,591-

To all whom it may concern:

Be it known that I, ORIE ELMER HAGA- MAN, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Propelling Devices; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in propelling devices.

The object of the invention is to provide a device of this character by the use of which air is employed for propelling vehicles.

A further object is to provide a propelling device which will be simple, strong, and durable in construction, eflicientin operation, and in which a maximum amount of propelling power is to be had with the least amount of resistance.

IVith these and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of the device, showing the application of the same to an ice-velocipede. Fig. 2 is a detail vertical sectional view of the device removed from the velocipede, and Fig. 3 is a similar view taken at right angles to Fi 2.

ReIerring more particularly to the drawings, 1 denotes avelocipede having a suitablyconstructed frame 2, which is supported upon runners 3, whereby the same is adapted to travel over ice or snow.

In the frame 2 of the velocipede is mounted the propelling device 4, which consists of an open cylindrically-shaped frame comprising end wheels or bands 5, having hubs 6 and spokes 7. The wheels or bands 5 are connected together by cross-bars 8, of which there are preferably three spaced equidistant apart around the wheels and are preferably secured thereto by forming on each end of the bars two threaded bolts 8 These bolts 8 are adapted to pass through pairs of apertures formed in the rim of the wheels and to have screwed on their outer ends nuts 8, thereby holding the bars in place and the wheels together.

The wheels 5 are journaled upon the laterally-projecting spindles of an arch or U- shaped axle, which is suitably mounted in the frame 2 of the velocipede, and on the hub of one or both of said wheels is arranged a sprocket-pinion 9. This sprocket-pinion 9 is connected by a chain 10 with a sprocket-pinion 11 on a shaft 12, which is journaled in the frame of the velocipede and on which is also mounted a sprocket-wheel 13, which is connected by a chain 13 to a sprocket-pinion 14 on the crank-shaft of the velocipede and to which is attached pedal-cranks 14, by which said propelling device is operated. A seat 15 is also arranged on the frame 2 to accommodate the operator and rider.

On the cross-bar 16 of the U-shaped axle near the ends of the same are revolubly mounted bearing disks or cones 17, which have an antifrictional engagement with said bar. In said disks or cones are mounted three cross rods or bars 18, which are arranged at equal distances apart around said cross-bar 16 of the axle.

To each of the cross-bars 8, which connect the rims of the wheels 5, are secured one edge of flexible wings 19, formed of canvas or similar material. Said bars have preferably formed therein longitudinally-(lisposed slots in which said edges of the wings are secured. The opposite edges of the wings are buckled or otherwise secured to the rods or bars 18.

On the outer end of one of the spindles of the U-shaped axle is secured a controllinglever 20, which is adapted to be grasped by the operator and turned to reverse the position of the U-shaped axle, thereby turning the wings out of operative position and into a position where they will retard the advance of the vehicle, and thus stopping the same. A suitable rack 21 is employed for holding the controlling-lever in operative or inoperative position.

In operation the cylindrical frame is rapidly revolved on the spindles of the shaft through the action of the pedals, and in so revolving the wings 19 are brought round into position to engage or beat the air, thereby propelling the vehicle rapidly over the ice or snow. As the wings are moved out of working position by the cylinder they fold together, thereby preventing any resistance or back action of the air on the same.

While the propelling device is here shown as being applied to a velocipede, it is obvious that the same may be applied to any vehicle and will be found to be particularly well adapted for use as a propelling device for airships and the like, and instead of being manually driven, as herein shown and described,

the same may be-readily geared to and run by any suitable motor.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the inven tion will be readilyunderstood without requiring a more extended ex lanation.

Various changes in the orin, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a propelling device of the character described, the combination with a suitable support, of a frame revolubly mounted thereon, wings connected to said support and to said frame whereby when the latter is revolved the wings are brought into and out of operative position, substantially as described.

2. In a propelling device of the character described, the combination with a suitable support, of a cylindrical frame revolubly mounted thereon, means whereby said cylindrical. frame is revolved, flexible wings secured to said support and to said cylindrical frame whereby when the latter is revolved said wings are brought into and out of opera tive position, substantially as described.

3. In a propelling device of the character described, the combination with an arched or U-shaped axle, of a cylindrical frame revolubly mounted thereon, means whereby said frame is revolved, flexible wings secured to said arched axle and to said frame whereby when the latter is revolved said wings will be successively. brought into and out of opera tive position, substantially as described.

4. In a propelling device of the character described, the combination with an arched or U-shaped axle, having laterally-projecting bearing-spindles, of a cylindrical frame revolubly mounted on said spindles, said frame consisting of two wheels spaced apart and connected together by cross-bars arranged at equidistant points around said rims and flexible wings secured at one end to said arched axle and at their opposite ends to the crossbars of said cylindrical frame, and means whereby said frame is revolved to successively bring said wings into and out of operative position, substantially as described.

5. In a propelling device of the character described, the combination with an arched or U-shaped axle having laterally-projecting spindles, and a cross-bar, of a cylindrical frame revolubly mounted on said spindles, said frame consisting of wheels spaced apart and connected together by slotted cross-bars secured at equidistant points around the rims of said Wheels, bearing-disks arranged on the cross-bar of said axle, wing-attaching bars having their ends mounted in said disks and arranged at equidistant points around said cross-bar, flexible wings secured at one end in the slots of said cylinder cross-bars and adjustably connected at their opposite end to the rods around said axle cross-bar, and means whereby said cylinder is revolved to successively bring said wings into and out of operative position, substantially as described.-

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
